4 Claims.

when such is provided, is pivotally mounted so as "to rest when in closed position on top of the seat. This construction is objectionable for a number of reasons. It is unsightly and occupies too great a space. Further, as the seat and cover areusually pivotally attached to the same fittings, which lo extend either from the adjacentwall or from the bowl itself, a relatively complicated fitting, or fittings, must be employed in order to havethecover and the seat function properly with respect to each other.

" In my present invention I have devised an improved combination of a seat and cover for defecators in which the stationary supporting means for the hinge elements of the same are positioned Wholly above the top of the bowl; This results in a construction which is easily kept clean, and in which the usual tarnishing of the metal of which the stationary support is composed is not ordinarily hastened as in prior constructions, where such support is continually wet by careless cleaning or otherwise. Further, in my construction the seat and cover are superimposed with respect to each other, the cover being uppermost, and the combined height of the two elements is but a 4 fraction of the usual combined height of both ele- -ments. This is due to the fact that the cover is of the enclosing type and further, the pivoting means for such combined structure is situated approximately midway between the top and bottom horizontal planes of the cover and seat re- "'spectively. Also, in my device I have arranged a stop element for either the seat or the cover, or for both, and which operates in conjunction with horizontal hinge posts on which same are pivotally mounted.

" A particular feature of my invention resides in the making of the cover with a hollow, shallow chamber in its lower face, conforming generally to the contour of the upper face of the seat, and which seat houses practically entirely within such hollow chamber, to the extent that the lower plane in which the lower face of the seat is located is also coextensive with the horizontal plane in which lies the lower surface of the cover.

My improved seat and cover are preferably adapted to be utilized in connection with specific mounting means and in association with means for securing the toilet bowl in position against awall, either to the wall directly, or to-the wall in conjunction with a vertically arranged supporting means associated with a wall, such, for example, as in the construction disclosed in my co-pending application, Serial No. 25,474 filed June 7, 1935.

In the accompanying drawing:

Fig. 1 is a perspective view of my improved construction applied to a wall type of defecator;

Fig. 2 is a side elevation'of a portion of a-wall' orbrackettype of defecator showing my improved construction, partly in section, in operative position thereon.

Fig. 3 is a sectional end viewtaken on line 3-3 15 The bolts referred to extend outwardly beyond 30*" the limits of the members I2, and such members are provided on their outer ends with cylindrical recesses to house the cylindrical ends of hingeposts I3. The cylindrical ends of the hinge posts I3 are internally threaded, as indicated by I3a, to screw onto the threaded end ofthe bolts re-' ferred to. The hinge posts I3 have formed integral therewith at the front ends thereof substantially rectangular shaped bearing members I 4 drilled to receive, as a rotating fit, the pivot shaft I5. The pivot shaft I5 is threaded at each endto receive cap nuts It, as will be hereinafter de scribed. It will be obvious from the'above description that the adjustment of the hinge-posts I3 is independent of the securement of the defe- 45 cator lll 'on a wall or other support.

I'I designates a defecator seat which has formed integral therewith at its rearward end, a transverse member I8 through which extends a tubular bearing member IS, the internal diameter 50 of such tubular bearing I9 being slightly greater than the external diameter of the shaft I5, so that the defecator seat I1 is rotatable about the shaft I5 in the usual manner. The width of the rearwardly extending transverse member I8 is 55 slightly less than the distance between opposing faces of the substantially rectangular bearing members I4, as clearly shown in Fig. 4. 20 designates a seat cover which has an outline slightly larger than, but similar to, the outline of the seat IT. The seat cover 20 has formed in its under face a shallow chamber 2| which conforms generally, both in size and shape, to the size and shape of the seat I1, so that when the cover 2| is in the dot and dash position shown in Fig. 2, it completely encases all of the seat I! above the lower face thereof and hides the same from view. The manner in which this enclosing action takes place is clearly shown in Fig. 3.

The cover 28 at the opposite sides of the rear end thereof has formed integral therewith, lugs or ears 22 in which are positioned bearing sleeves 23 adapted to be rotatably mounted on the shaft l5, and when in proper position thereon the cap nuts "5 are screwed onto the threaded ends of the shaft l5, washers 24 being placed between cap nuts l8 and the outer faces of the lugs or ears 22.

Also formed as an integral part of the cover 20 at the rearward end thereof is an extension 25, the under face of which conforms generally to the contour of the extension l8 of the seat H. The extension 25, together with the lugs or cars 22 form the groove 26 which, when the cover 20 is rotated on shaft 15 from the dot and dash position shown in Fig. 2 to the full line position shown in such Fig. 2, engages with the bevel faces of the bearing members l4, disposed beyond the dead center of the shaft l5, and thus acts as a means for limiting further rotary movement of the cover 20. This construction, while permitting the cover 2| to rotate sufficiently to allow same to rest substantially upright as shown in Fig. 2, prevents same from rotating so far as to strike against the wall of the bathroom in which the device is presumably located.

As will be seen from inspection of Fig. 2, the center of the shaft [5 is located well within the zone between the horizontal plane in which lies the top surface of the cover 20, as designated by the dot and dash lines and the horizontal plane in which lies the under surface of both the seat I! and the cover 20. There are thus no protruding devices or obstructions. Further it will be noted that the horizontal hinge posts [3 lie well above the horizontal plane in which lies the top surface of the defecator In.

My device is well adapted not only for new constructions but also for use in replacing present seats and covers in existing plumbing installations and is not to be limited merely to use in connection with a bracket type of defecator, such as designated by the numeral I0.

While I have shown and described preferred form of my invention somewhat in detail, it is to be understood that I may vary the size, shape and arrangement of parts comprising my device within the relatively wide limits without departing from the spirit of the invention.

I claim:

1. In combination, a defecator bowl, a defecator seat lying in a substantially horizontal plane and resting on said bowl, a defecator seat cover normally lying in a substantially horizontal plane and resting on said seat and when in such position having its lower circumferential surface lying in substantially the same plane as the lower' surface of the seat, a horizontal pintle positioned substantially between the horizontal plane in which lies the upper surface of the seat cover and the horizontal plane in which lies the lower surface of the seat and seat cover, means extending rearwardly and upwardly from the seat to support it for pivotal movement about the axis of said pintle and means extending rearwardly from said seat cover to support it for pivotal movement about the axis of said pintle.

2. In combination, a defecator seat and a defecator seat cover hingedly supported on a common shaft positioned adjacent to the rear edge of the seat and cover and within the confines of such seat and cover, supports for said shaft, a chamber formed in the under face of the seat cover and acting as an inclosure for the seat when in closed position on a defecator, and a stop, formed integral with the seat cover and cooperating with the shaft support for limiting the upward and rearward movement of said seat cover to a distance sufficiently back of the dead center whereby to provide a rest for the seat against the seat cover beyond the dead center position of the seat.

3. In combination with a defecator bowl, a defecator seat and cover therefor hinged on a common pintle, the said pintle being positioned between the upper surface of the cover and the lower surface of the seat when the cover is in its closed position and being journaled adjacent its ends in mutually spaced hinge posts extending substantially horizontally from a supporting member and disposed between the said upper surface of the cover and the said lower surface of the seat when the cover is in its closed position, said cover having stop members formed adjacent the locations of journaling for cooperation with the hinge posts in limiting the extent of opening of saidcover with respect to the seat and for providing a rest for said cover when in its open position.

4. In combination with a defecator bowl, a seat adapted to rest directly on the upper surface of the rim of said defecator bowl and to extend over at least the area thereof, and a cover for the seat comprehending substantially the entire superficial area thereof together with the space enclosed thereby with the exception of the lower surface thereof, said seat and said cover being hinged on a common pintle journaled in mutually spaced hinge posts extending horizontally, between the upper surface of the cover and the lower surface of the seat when the cover is in its closed position, from a supporting member, and stops formed in said cover adjacent the 10- cations of said journaling for cooperation with stops provided by said hinge posts in limiting the extent of possible opening of the cover relative to the seat and providing a position of rest for the cover when raised.
